Efficient storage of microCT data preserving bone morphometry assessment
Preclinical micro-computed tomography (microCT) images are of utility for 3D morphological bone evaluation, which is of great interest in cancer detection and treatment development. This work introduces a compression strategy for microCTs that allocates specific substances in different Volumes of Interest (VoIs). The allocation procedure is conducted by the Hounsfield scale. The VoIs are coded ...
متن کاملLimitations of global morphometry in predicting trabecular bone failure.
Efforts in finding independent measures for accurate and reliable prediction of trabecular bone failure have led to the development of a number of morphometric indices characterizing trabecular bone microstructure. Generally, these indices assume a high homogeneity within the bone specimen. However, in the present study we found that the variance in bone volume fraction (BV/TV) in a single bone...
متن کاملThe past, present, and future of bone morphometry: its contribution to an improved understanding of bone biology.
It was not until the 1950s that a better paradigm for bone biology evolved, which led to the birth of bone histomorphometry. Two clinicians, Harold Frost (1958-1964) and Lent Johnson (1964), were responsible for the paradigm stating that the primary function of bone is mechanical load bearing with subsidiary function to participate in plasma calcium homeostasis to support hematopoesis. Dynamic ...
متن کاملDigital vertebral morphometry performed by DXA: a valuable opportunity for identifying fractures during bone mass assessment.
OBJECTIVES To evaluate the usefulness of vertebral morphometry in identifying unreferred vertebral fractures and correlate potential risk factors. SUBJECTS AND METHODS Female patients above 45 years, postmenopausal for at least 2 years, diagnosed with osteoporosis and undergoing treatment for at least three months were considered eligible. All of them underwent bone densitometry and vertebral...
متن کاملThree dimensional visualisation and morphometry of bone samples studied in microcomputed tomography (micro-CT).
This article highlights the utility of micro-computed tomography (micro-CT) for characterisingmicroscale bone morphology. For this purpose we tested selected samplesof the human bones (Wormian bone, rib, lumbar vertebra) to reconstruct externaland internal morphological features. Selected bony samples were investigatedusing a micro-CT scanner (Skyscan 1172, N.V., Aartselaar, Belgium). The image...
